王明昌博客PhpSpreadsheet是一个纯PHP类库，使你能够读写Excel、LibreOffic Calc等这样的表格格式。

坑
列从0开始算，行从1开始算
$sheet->setCellValueByColumnAndRow(0,1,‘特别说明‘);
安装
composer require phpoffice/phpspreadsheet 版本号
默认情况会提示找不到库，上composer找是有的，是因为还没有稳定版，所以要指定版本 1.0.0beta
依赖
The following software is required to develop using PhpSpreadsheet:
- PHP version 5.6 or newer
- PHP extension php_zip enabled
- PHP extension php_xml enabled
- PHP extension php_gd2 enabled (if not compiled in)
默认使用ZipArchive来压缩保存
注意读写权限
简单示例
|
1 2 3 4 5 6 7 8 9 10 11 12 |
require ‘vendor/autoload.php‘; use PhpOffice\PhpSpreadsheet\Spreadsheet; use PhpOffice\PhpSpreadsheet\Writer\Xlsx; $spredsheet = new Spreadsheet(); $spreadsheet = new Spreadsheet(); $sheet = $spreadsheet->getActiveSheet(); $sheet->setCellValue("A1", 'Hello World !'); $writer = new Xlsx($spreadsheet); $writer->save('hello world.xlsx'); |
默认保存到执行php的根目录，以thinkphp为例index.php在D:\wwwroot\thinkphp\public，那么文件就保存在这
注：如果不想保存到文件，可以传入php://output或php://stdout直接输出（例如html，输出网页）
通过模板来生成文件
全用代码写太累，可以用模板来修改，但是对于动态数据，还是要由代码生成
|
1 2 3 4 5 6 7 8 9 10 |
//通过工厂模式创建内容 $spreadsheet = \PhpOffice\PhpSpreadsheet\IOFactory::load('template.xlsx'); $worksheet = $spreadsheet->getActiveSheet(); $worksheet->getCell('A1')->setValue('John'); $worksheet->getCell('A2')->setValue('Smith'); //通过工厂模式来写内容 $writer = \PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet, 'Xls'); $writer->save('write.xls'); |
释放内存
为了防止内存泄露，建议用完手动清理
|
1 2 |
$spreadsheet->disconnectWorksheets(); unset($spreadsheet); |
单元格
根据索引获取英文列
其中A=0
Cell::stringFromColumnIndex($pColumn)
设置值
|
1 2 3 |
$worksheet->getCell(‘A1‘)->setValue(‘John‘); $sheet->setCellValue(‘A1‘, ‘Hello World !‘); $sheet->setCellValueByColumnAndRow($columnIndex, $rowIndex, $value); |
宽度设置
$this->getColumnDimension($columnIndex)->setWidth($width);
还可以让其自适应（不靠谱，建议自行设置）
$sheet->calculateColumnWidths();
直接输出下载
|
1 2 3 4 5 6 |
header(‘Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet‘);//告诉浏览器输出07Excel文件 //header(‘Content-Type:application/vnd.ms-excel‘);//告诉浏览器将要输出Excel03版本文件 header(‘Content-Disposition: attachment;filename="01simple.xlsx"‘);//告诉浏览器输出浏览器名称 header(‘Cache-Control: max-age=0‘);//禁止缓存 $writer = new Xlsx($spreadsheet); $writer->save(‘php://output‘); |
自动计算列宽
|
1 2 3 4 5 6 7 8 9 |
function autoFitColumnWidthToContent($sheet, $fromCol, $toCol) { if (empty($toCol) ) {//not defined the last column, set it the max one $toCol = $sheet->getColumnDimension($sheet->getHighestColumn())->getColumnIndex(); } for($i = $fromCol; $i <= $toCol; $i++) { $sheet->getColumnDimension($i)->setAutoSize(true); } $sheet->calculateColumnWidths(); } |
